Application

1. it adopts the closed cycle structure and can simulate wellbore condition and return velocity of drilling fluid and select bridging material with excellent effect, drilling fluid and completion fluid;
2. can evaluate sealing effect of mud under wellbore condition;
3. can measure maximum sealing capacity of bridging material and flowback pressure.
4. applied to prevent collapse test of shale;

The apparatus is a very important part of a research, which was award the second award of national science and technology progress.
